The best way is to use an HTTPHandler. Essentially these are classes which "trap" the server request for any kind of file you want (in this case, a .pdf file) and process the class instead. Lets look at a compression HttpModule: class AlHttpModule : IHttpModule { public AlHttpModule() { } #region IHttpModule Members public void Dispose() { // Clean any resources you may used } public void Init( HttpApplication context) { context.BeginRequest += new EventHandler (context_BeginRequest); } #endregion public void context_BeginRequest( object sender, EventArgs e) { HttpApplication app = ( HttpApplication )sender; string encodings = app.Request.Headers.Get( "Accept-Encoding" ); // No encodings stop the HTTP Module processing if (encodings == null ) return ; if (app.Request.Url.AbsolutePath.IndexOf( ".aspx" ) == -1 && app.Request.Url.AbsolutePath.IndexOf( ".asmx" ) == -1 ) return ; Stream baseStream = app.Response.Filter; encodings = encodings.ToLower(); if (encodings.Contains( "gzip" )) { app.Response.Filter = new GZipStream (baseStream, CompressionMode .Compress); app.Response.AppendHeader( "Content-Encoding" , "gzip" ); } else if (encodings.Contains( "deflate" )) { app.Response.Filter = new DeflateStream (baseStream, CompressionMode .Compress); app.Response.AppendHeader( "Content-Encoding" , "deflate" ); } } }
